is FoxTab Video Converter safe to download

I'm looking for some software that'll help me with an 'unsupported file' when I try to watch an MP4 or AVI movie after downloading. It seems from my research that FoxTab Video Converter may be the answer. Yet when tried opening the application my Kaspersky Internet Security warned that this a potentially harmful programme as it has no signature. Is it safe to use?

FoxTab Audio Converter does NOT convert mp4 to mp3. I downloaded and found out its limitations. I want to remove it but it does not show up in the program files list under the control panel. I would love to remove it but do not know how. If anyone knows how to remove this bogus program please let me know. Thanks in advance for the help!
